PIN DESCRIPTIONS
PIN NAME
DESCRIPTION
Voltage Feedback Input. The voltage at this pin is regulated to 5.10V. Connect this pin to the
1 CSP positive terminal of current sense resistor. CSP, CSN1 and CSN2 Kevin sense is
recommended.
2 CSN1 Output current sense. Connect to the negative terminal of current sense resistor for VOUT1.
3 CSN2 Output current sense. Connect to the negative terminal of current sense resistor for VOUT2.
Mode pin with internal pull up current to determine device should operate in Native, Master,
4
MODE
or Slave mode. If the pin is floated, the device operates in native mode; if the pin is
grounded ,the device operates in Slave mode and receives CLK signal from another device;
if the pin is connected to 82kOhm resistor, the device is configured in Master mode.
5
CLK
Synchronization of dual chips. Two chips operate synchronously out of phase with CLK pin
connected.
6
IN
Power Supply Input. Bypass this pin with a 10μF ceramic capacitor to GND, placed as close
to the IC as possible.
7 SW Power switching output to external inductor.
8
HSB
High Side Bias pin. This pin provides power to the internal high-side MOSFET gate driver.
Connect a 22nF capacitor from HSB pin to SW pin.
9
GND
Ground and heat dissipation pad. Connect this exposed pad to large ground copper area
and other ground planes by thermal vias.
